I really like the idea of using Skype to bring experts into the classroom. That could have been a super useful tool as a middle school teacher in rural Louisiana. However, on the middle-high school level, using Skype to incorporate experts could also present special challenges;  for example when the school day incorporates many periods, ensuring that all classes have the same access to experts could be difficult. Nonetheless, I 'm sure that with proper planning and creative thinking, such issues could be mitigated.

Skype would be equally useful for incorporating experts into the classroom on the college level.

Also, I like the potential for using Skype or other techniques to allow "contagious but capable" sick students to still "attend" class, or to provide chronically sick children some degree of normalcy in their lives.
